New Delhi: Describing the clean chit given to Sonia Gandhi's son-in-law Robert Vadra by Haryana government as a "self-certification", BJP on Friday said there was no reason to believe in the findings of the probe by state authorities.

It also demanded a fair inquiry into Vadra's claim that he had received an overdraft of Rs 7.94 crore from Corporation Bank which the latter has denied.

"The clean-chit given by the Haryana government to Robert Vadra in the land deals is a self-certification.

"What else can they do? They are the accused, the investigators and the ones giving the clean chit. But in the case of Rs 7.5 crore overdraft from Corporation Bank which Vadra, his mother and his CA have claimed should be investigated," BJP spokesperson Prakash Javadekar said.

Speaking in Kanpur, party leader Rajnath Singh said, "You are talking about the Deputy Commissioners of the Government. Now if the allotment has been done by them only, how can say that it is wrong. So I feel that that there is no reason to believe in it."

Singh demanded an impartial inquiry in the land deals monitored by Supreme Court.

"I believe that truth will come out only if an impartial inquiry under Supreme Court is done in such cases," the former BJP president told reporters.

The Opposition sought to know why the Finance Ministry, the Income Tax department, the Enforcement Directorate and other officials are silent on the Corporation Bank issue.

"Vadra cannot lie, and his CA can definitely cannot lie. So that would mean the Bank is lying. BJP wants to know where this Rs 7.5 Cr came from," Javadekar said.

"A national bank has said it had not issued this overdraft. This Rs 7.50 crore, plus Rs 50 Lakh were converted into Rs 58 crore later," Javadekar said, referring to the money reportedly invested by Vadra in DLF and the return he got.

"So who is lying in this case? Why is the Corporate Affairs Ministry silent on this issue? Why is it not probing this matter?" Javadekar said.

BJP also attacked Congress General Secretary Digvijay Singh and sought to know why CBI is not probing the case against him despite a High Court order to do so.

The party alleged that Singh had indulged in misuse of power in Madhya Pradesh."Digvijay Singh should explain what X-299 stands for.He had written this next to his signature. Is it a code or a password?" Javadekar said.

On corruption allegations on BJP president Nitin Gadkari, Rajnath Singh said that Gadkari has offered himself for an open probe by any government agency.

"No other leader from any party who has been accused of corruption has taken such a courageous step," Singh said.

He said that Gadkari was not sitting on any public post and still he has challenged the government to probe the allegations against him by any agency.

When asked if Gadkari will resign from the post of party president, Singh said that "he is neither a parliamentarian nor holding a government post to influence the probe so why should he resign".

On being asked if Gadkari should get another term as BJP president, Singh said that the whole controversy will have no effect on Gadkari's election.

On various corruption allegations being levelled against political parties by activist Arvind Kejriwal, Singh said that "anyone can level allegations against parties but one should be cautious that such actions do not lead to lack of faith in constitutional authorities because that will put democracy in danger".

He said that in the history of independent India there has been no other party except Congress against which every day new corruption allegation were being levelled.

"This government has lost its credibility and mid-term elections can happen anytime. BJP is ready for elections," he told reporters.

Singh said that both the Bahujan Samaj Party and Samajwadi Party were hesitant to take back their support rom the UPA government as they were afraid that BJP could form government at the Centre.

"Though, the BJP has made it clear that we are willing for mid-term election rather than making government," he said.
